الملخص EN

The aim of this study is to determine the presence of informal housing that exceeds the basic urban plan for neighborhood (211 and 212) in lbb city, as well as to determine the percentages and areas of land use.

the study relies on field research, questionnaires, and the comparison of the basic urban design with satellite images of the two neighborhoods for the years 2008 and 2022.

In addition, spatial analysis was conducted on land use and the spatial distribution of informal housing using (ArcGIS 10.8 software).

the study concluded that there is an imbalance in land use in the study area according to planning standards and urban planning, with many planning problems and flaws in the basic plan design.

the study also observed a lack of implementation of the urban plan in reality.

the area studied showed a slight diversity in land use to meet the needs of its population, in addition to the randomness of urban expansion and horizontal growth and weak monitoring systems.

this has led to a continuous increase in the number of informal housing units, with the lowest percentage of informal housing and its area belonging to neighborhood (211), which has (101) informal residential buildings, representing (21.4%) of the total number of informal residential buildings in the study area, which is (473) buildings, and the total area of informal housing in it is (0.032724) km2, representing (21.4%) of the total area of neighborhood (211).

This is equivalent to (33.4%) of the total area of the study area of (1.4373) km2.

on the other hand, the area of neighborhood (212) is (0.9573) km2, representing (66.6%) of the total area, and the area of informal housing in it is (78.6%) of its total area, with (372) informal residential buildings, equivalent to (78.6%) of the total number of informal residential buildings in the study area.

this indicates that the high percentage of informal housing is concentrated in neighborhood (212) due to its large area and high population density.
